Why the xTool F1 Ultra Changed My Mind About Desktop Laser Engravers

I didn't think a desktop laser could handle metal. I was wrong.

Look, I've been managing equipment purchasing for our shop since 2022. When I first heard about the xTool F1 Ultra—a 20W dual laser engraver that claims to work on metal, glass, wood, and acrylic—I was skeptical. I've seen too many "do-it-all" machines that excel at nothing. But after running test pieces on brass, anodized aluminum, acrylic sheets, and even a wine glass over the past six weeks, I had to rethink my assumptions.

Here's the thing: the industry has changed. What was a niche capability in 2020 is now practical for small shops. And if you're evaluating metal engraving tools or a laser engrave machine for mixed materials, the F1 Ultra deserves a serious look.

1. The dual laser isn't a gimmick — it solves a real pain point

I'm not a laser engineer, so I can't speak to the technical nuances of beam coupling. What I can tell you from a buyer's perspective: having both a 20W fiber source and a 20W diode source in one compact chassis eliminates the need for two separate machines.

The fiber laser handles metals — brass, stainless steel, even some uncoated metals for marking. The diode laser handles organics — wood, leather, and acrylic for cutting and engraving. If you're asking yourself "what is the best acrylic for laser cutting?" the answer is usually cast acrylic for engraving and extruded for cutting, but the F1 Ultra's diode laser cuts both cleanly at up to 10mm thickness (depending on settings).

Three things to consider if you're buying for a shop:

• Metal engraving quality: On coated metals (e.g., anodized aluminum), the diode laser can mark, but the fiber laser gives you crisp, high-contrast engravings. For bare brass, fiber is the only option.
• Glass engraving: This surprised me. The diode laser frosted glass better than I expected — no cracking at low power.
• Rotary support: The included rotary attachment works for cylindrical objects (cups, bottles). It's not perfect for large diameters, but for standard drinkware it's solid.

I wish I could give you exact power and speed settings for every material. Truth is, I'm still dialing them in. But the xtool f1 ultra fiber laser specs (20W fiber, 0.5-5W adjustable power) are accurate for marking metals.

2. Performance vs. price: the trade-off you need to know

I have mixed feelings about the price. On one hand, the xTool F1 Ultra is more expensive than a standalone diode engraver. On the other, it's significantly cheaper than buying a separate fiber laser (which can run $3,000+ for a comparable 20W unit).

As of March 2025, the F1 Ultra retails around $1,800 (verify current pricing at xTool's site). For a small business or maker space, that's a reasonable investment if you need both metal and non-metal capabilities. But if you only cut wood and acrylic, a dedicated diode laser at $500-800 might be more cost-effective.

I still kick myself for not checking the acrylic cutting limits before I bought. The F1 Ultra's diode laser cuts up to 10mm thick acrylic in multiple passes. For thicker sheets, you'll need a CO2 laser. That's a limitation worth acknowledging.

Granted, for 90% of our projects (signage, tags, promotional items), 10mm is plenty. But if you regularly cut 12mm+ acrylic, this machine isn't ideal.

3. The real-world workflow improvements

Before the F1 Ultra, we had two setups: a cheap diode laser for wood and a rented fiber laser for metal jobs. Coordinating between them was a headache. With the dual laser, we switch materials in minutes, not hours.

This gets into operational efficiency territory, which isn't my strong suit. What I can tell you from a purchasing perspective: consolidating to one machine reduced our setup time by roughly 40%. (Based on our internal tracking in Q1 2025.)

Oh, and the software integration with XCS (xTool's Creative Space) is surprisingly decent. It has material presets, which saved me trial-and-error time. Should mention: the rotary attachment calibration was finicky at first, but once dialed in, it worked consistently.

4. Addressing the skepticism: is the dual laser a compromise?

I get the criticism. Two lasers in one chassis means neither is as powerful as a dedicated equivalent. A 20W fiber laser in a $3,000 standalone unit will be faster. A 20W diode in a $600 machine might have a larger work area.

That's fair. But for a desktop form factor under $2,000, the F1 Ultra delivers a combination that didn't exist in 2023. If you need occasional metal engraving and regular non-metal work, this is the most practical choice I've seen.

Here's the thing: most small shops don't need production-grade speed. They need versatility. The F1 Ultra gives you that without requiring a separate workshop, ventilation system, or dedicated fiber laser enclosure.

Bottom line

The xTool F1 Ultra isn't perfect. It has limitations on thick acrylic, it's not the fastest for metal, and the price is a step up from basic diode engravers. But for a small business evaluating metal engraving tools or a versatile laser engrave machine for mixed materials, this is the most sensible option I've tested in 2025.

The industry has evolved. Five years ago, you'd need two separate systems. Today, the F1 Ultra covers 80% of what most shops actually need. Sometimes the new tools really do change the game.
